TIP 120-0405 Light Array Ream Inspection

This upgrade is part of the Technical Improvement Program (TIP); it replaces the existing inspection sensors with Light Arrays as depicted in the reference image.

The light arrays require a fast response time and analog input card. The existing PLC cannot satisfy these needs, so it’s replaced by AB Compact Logix or Siemens S7 with all of the required I/O cards. The existing ream reject fault indicators and other switches will be replaced by a 7 in HMI for operator interface. This HMI will also be used to “teach” a new ream being run. To also improve the ream reject timing and precision, the existing 4-lobe scanner wheel will be replaced by a 8-lobe wheel along with a new sensor. The girth inspect eye will be replaced by a retro reflective eye thus eliminating all the fiber optic eyes on the machine.
